Inflation-free-wheel energy conversion system

The invention discloses an inflation-free-wheel energy conversion system comprising wheels. Each wheel comprises a rim and spokes. A plurality of air compressor pumps or reciprocating screw compressors are arranged along the annular surface, facing the ground, of each rim in an annular distribution mode. Tire rubber is independently arranged on the end face, contacting with the ground, of each air compressor pump or reciprocating screw compressor. Each air compressor pump or reciprocating screw compressor is provided with a reset spring and is connected with a generator arranged on the corresponding rim or a vehicle frame, and power generated by the air compressor pumps or the reciprocating screw compressors is utilized for electricity generation of the generators. During driving of a vehicle, rotation force or compressed air is generated when the ground applies acting force to the reciprocating screw compressors or the air compressor pumps, so that the rotation force or the compressed air generated continuou
